Description

A kind of rack drives gear takes off the mould that thread products, pin gate enter to water
Technical field
The present invention relates to the die casting of metal forming and the injection molding of plastic shaping, is the mould that the de-thread products of a kind of rack drives gear, pin gate enter to water.
Background technology
At present, at mould, manufacture boundary, in the design of de-thread products, have: (1) hand ejection, it is before mould molding, by artificial elder generation, thread core is arranged on to the relevant position of mould, after moulding, mold ejection mechanism thread core together with goods outside launch mode, then at mould external application special fixture, goods are separated with thread core by staff.The mould structure of this mechanism is simple, and die cost is low, but its production efficiency is low, and in the process of artificial Separation Product, scrappage is high, and when thread core is installed, safety of workers can not get ensureing.(2) mold mechanism of motor, hydraulic pressure, air pressure automatic trip screw thread.It is the motor, hydraulic cylinder, the pneumatic cylinder that are arranged on mould lateral surface be the thread core that power carrys out driven mold, goods are deviate from rotation.This mold mechanism action is solid and reliable, pressure transmission is good, automaticity is high, but when Mould Machining is manufactured, process more auxiliary component motor, hydraulic cylinder, cylinder are installed, this brings very big inconvenience to a line manufacture, installation, debugging, maintenance, the processing and manufacturing time is long, and new product release can not get temporal guarantee.Because motor, hydraulic cylinder, cylinder are mounted in mould lateral surface, therefore the volume of mould increases, so just cause die cost high, the rotation of thread core is not simultaneously that the power of the folding mould of pattern tool own realizes, that motor, hydraulic cylinder, cylinder outside pattern is that power rotates, therefore must select special-purpose injector to carry out injection moulding, produce and bring limitation like this to production line, production cost increases substantially.
Summary of the invention
The present invention is to provide the mould that the de-thread products of a kind of rack drives gear, pin gate enter to water, it is to utilize the tooth bar that is arranged on stationary mould for mould one side, drive is arranged on the bevel gear in mould dynamic model one side's gear driven mould, to the thread core of mould, force thread core rotation to reach the object of goods transmission of power.In the design of running gate system, it is the spring of installing between top clamping plate and cavity plate, when die sinking, because cavity plate loses pressure, so spring also loses pressure, and so far spring is just upspring, due to upspringing of spring, just force cavity plate action forward on pull bar, the pin gate of running gate system part is just cut off automatically with product like this, and then the solidifying material of running gate system just drops out (as shown in Figure 2) mould between top clamping plate and the gap of solid plate.A kind of rack drives gear takes off thread products, the mould that pin gate enters to water, it is characterized in that: spring (1) is arranged in the hole of top clamping plate (6), pull bar (23) is slidably matched with cover half cavity plate (5) after being arranged in the stepped hole of top clamping plate (6) again, centring ring (7) is locked in the stepped hole of top clamping plate (6) with the first screw (13) and the second screw (10), tooth bar (24) is arranged in the stepped hole of top clamping plate (6), the first axle (22) is slidably matched with mould pin (3), be arranged on the first bevel gear (14) on the first axle (22) and be arranged on the second bevel gear (16) on the second axle (15) and nibble shape and coordinate, the second gear (17) be arranged on dynamic model backing plate (4) upper after again with the 3rd gear (19) immovable fitting being arranged on thread core (18), thread core (18) is slidably matched with push piece plate (8).A kind of rack drives gear takes off thread products, the mould that pin gate enters to water, the mould production efficiency that it has solved manual de-thread products is low, in the process of artificial Separation Product, scrappage is high, when thread core is installed, safety of workers can not get the problem ensureing, solved motor, hydraulic cylinder, the mould of the de-thread products of pneumatic cylinder will be processed more auxiliary component motor is installed, hydraulic cylinder, cylinder, this gives a line manufacture, install, debugging, maintenance brings very big inconvenience, the processing and manufacturing time is long, new product release can not get the problem of temporal guarantee.Solved because motor, hydraulic cylinder, cylinder are mounted in mould lateral surface, therefore the volume of mould increases, so just cause die cost high, the rotation of thread core is not simultaneously that the power of the folding mould of pattern tool own realizes, that motor, hydraulic cylinder, cylinder outside pattern is that power rotates, therefore must select special-purpose injector to carry out injection moulding, to production line, produce the problem of bringing limitation, production cost to increase substantially like this.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described

Sectional side elevation when Fig. 2 is mould die sinking
In figure, numeral number represents respectively:

The specific embodiment:
Shown in figure, it is the de-thread products of a kind of rack drives gear, the mould that pin gate enters to water, when clamping mould in injector through cast, pressurize, cold moving rear mold is opened, goods (20) are moved to dynamic model one side from cover half cavity plate (5) by thread core (18), when the gap of die sinking to push piece plate (8) and cover half cavity plate (5) is greater than after the height of goods (20), have toothed portion and first gear (9) of stationary mould for mould one side's tooth bar (24) mesh, at this moment mould dynamic model partly continues action, tooth bar (24) drives the first gear (9) rotation, rotation due to the first gear (9), drive the first bevel gear (14) and the second bevel gear (16) rotation, second gear (17) being arranged on the second axle (15) that rotarily drives of the second bevel gear (16) rotates, at this moment the second gear (17) drives thread core (18) rotation being arranged on the 3rd gear (19), rotation due to thread core, the threaded portion of goods (20) and thread core (18) are while becoming flexible under the thrust of push piece (8) to deviate from outside mould.On the other hand, the solidifying material of running gate system (21) is after stationary mould for mould and dynamic model are opened, cover half cavity plate (5) loses pressure, because cover half cavity plate (5) loses after pressure, and at this moment spring (1) also loses pressure, therefore spring (1) is upspring and is forced cover half cavity plate (5) to be moved forward, at this moment the pin gate part on the solidifying material of running gate system (21) is cut off automatically with goods (20), the elastic force of spring separates cover half cavity plate (5) and top clamping plate (6), when gap separation is greater than the height overall of the solidifying material of running gate system (21), cover half cavity plate (5) is no longer moved in the effect lower limit of limit pull rod (23), now the solidifying material of running gate system (21) drops out mould between gap by deadweight.
